2.2.1 is a ((stable)) beta. There is no real 2.3 ATM.
Then perhaps we should call it 2.2.9 or something like that?
Point is, the time gap between 2.2.1 and 2.3 is huge. The feature gap between 2.2.1 and 2.3 is huge. There has been a lot of work on 2.3, and playable but buggy releases are being released for people to play with.
Heck, as pointed out, the Wiki documents 2.3 more than it documents 2.2.1. Some of the developers have been working on 2.3 for so long that they cannot answer questions about 2.2.1. Bug reports based on 2.2.1 are so out of date that they are of no use anymore.
As much as 2.2.1 is the current released beta, and
2.3 2.2.9 is alpha, everything I've read on these forums in the last few days indicated that 2.2.9 is currently at least as good as 2.2.1. So people want to play it, and have questions about it.
Now, are you really going to say that with the wiki describing 2.3, the developers talking about 2.3, bug reports only being useful if they are 2.3, and more features in 2.3, that we cannot talk about playing 2.3 on the forums?
